STONE Serial Touch Screen Display
The STONE serial touch screen has a wide range of USES, covering civil, medical, precision measuring instruments, and other fields. Now, I’m going to use a 5-inch STONE serial HMI screen to make a simple electronic scale.
The Following Modules Are Needed
STONE STVC050WT-01 touch screen serial port display module
STM32F103RC development board
Pressure acquisition module
ADC conversion module

The capacitive touch screen is a four-layer composite glass screen. The inner surface of the glass screen and the interlayer are coated with one layer of ITO respectively. The outermost layer is a thin layer of silica soil glass protective layer. When the finger touches the metal layer, the user and the touch screen surface form a coupling capacitor due to the electric field in the human body.
The capacitor is a direct conductor to the high-frequency current, so the finger sucks a small current away from the contact point. The current flows from the electrodes at the four corners of the touch screen respectively, and the current flowing through the four electrodes is proportional to the distance from the fingers to the four corners. The controller calculates the precise proportion of the four currents to get the position of the touchpoint.
